Wastewater contamination is an ever increasing problem which the whole world is facing now. Industrialization & globalization has led to the tremendous increase in use of heavy metals over the past decades. This has gradually resulted in increased flux of metallic wastes in marine, ground, industrial &even treated waste waters. As far as the modern treatment processes are concerned, removal of heavy metals are very expensive, require high energy and generate toxic sludge which pose serious threat to the whole ecosystem. Nowadays, the uses of natural, low cost & effective adsorbents are being highly recommended. As well as the method of bio sorption can help in removing heavy metals to a greater extent. For this project, agricultural waste i.e. Tea waste is used as bio sorbent for the removal of heavy metal like, chromium, cadmium & lead. With this new combination, it is possible to produce pollutant-free water & pollution-free ecosystem thereby reducing metallic pollution at low cost, simple, efficient & by natural means. In the present study, heavy metal contamination in textile industrial waste water has been discussed .The conventional methods of treatment are very costly, energy intensive and generate toxic sludge. Thus, the bio-sorption has been investigated as cost effective method for removal of heavy metals. The study involves the examination of experimental conditions such as pH of the solution, concentration of the solution, contact time and adsorbent loading on the removal of heavy metals from textile industry. Finally, the maximum adsorption of 96% is achieved by adding 1.0 g of tea waste per 100 ml of wastewater.
